A brilliant and fashionable assemblage gathered at noon yesterday in the Church of the Heavenly Rest, on Fifth-avenue, to witness the marriage of Miss Florence Schieffelin, a daughter of George R. Schieffelin and a great favorite in New-York society, and Mr. J. Bruce Ismay, the Agent of the White Star Steamship Line. Mr. Schieffelin and his family are members of Grace Church, but selected the Church of the Heavenly Rest for the ceremony on account of its proximity to their residence on Forty-fifth-street. The Rev. Dr. Huntington of Grace Church, assisted by the Rev. D. Parker Morgan, the Rector of the Church of the Heavenly Rest, were the officiating clergymen.

The bride wore a gown of white brocade richly trimmed with old point lace. A veil of old point also fell over her face, confined by a tiara of diamonds. A diamond pendant hanging from a necklace of pearls sparkled at her throat. She carried a large bouquet of lilies of the valley. Preceding her were the two little maids of honor, her sisters, Miss Sadie and Miss Constance Schieffelin, who wore white silk dresses, white hats, and carried baskets of pink roses. The ushers were Messrs. Bond Emerson, T. J. Oakley Rhinelander, Amory Sibley Carhart, Edward
Perry, and Fleming Crooks of England. The groom's best man was Mr. Ernest Bliss.

At the conclusion of the ceremony a wedding breakfast was given to the young couple and their intimate friends at the residence of the bride's father, 8 East Forty-fifth-street. Among those present were Mr. John Jay, Mrs. Ernest Crosby, Mr. and Mrs. James Beekman, Mr. and Mrs. William Rhinelander, Mr. and Mrs. Philip Rhinelander, Mr. and Mrs. William Schieffelin, The Misses Rhinelander, Miss Fannie Walker, the Misses Webb, Mrs. W. S. Livingston, Miss Eleanor Robinson, Mrs. Eastman Johnson, Miss Johnson, and Miss Marie Van Deuser Reed.
